I came back home after dark and stood in the yard looking at the sky and trees. As my eyes adjusted to the darkness I saw glowing sections of the ground. I knelt down and felt the glowing objects and realized that they were roots. So I lay down next to the glowing roots and marveled.
Later in a dream, I saw that they were pine roots.
Today I finished trimming the window and installed the first level floor and insulated it.
